General descaz'ptz'oa.

In' the embodiment of my invention here shown, the lastv comes to the machine with the rubberized cloth lining and other inner parts of the shoe applied thereto, and,'the

last-being supported, right side up, upon a pedestal, the machine applies over these lasted. parts a fiat, vulcanizabla sheet rubber upper or 'vamp of the usual form, joins its wings or heel portions in' a seam at the heel, and presses its toe marmn around theedge of the sole. y

The instrumentalities for so manipulating the vamp comprise a flexible U-'shaped toestock-anclioring member or toe-stretcher adapted to receive and adhesively` hold the loe-margin ot' the fiat vamp as the' latter is laid `thereon in an inverted, horizontal position. with its loe portion adjacent the toe ofthe last, a pair of heel-stock-anchoring members or heel-stretchers adapted concurrently so to receive and hold the heel margins'ot' the wing portions of the vamp, means for so moving the toe-stretcher; and heel-stretchers as to turn andv move the vamp over onto the last, lthe vamp .turning over its toe-portion, roughly, as a Center, means for turning the heel-stretchcrs 'Froinfa horizontal lo a. vertical plane to carry the wings oli the vamp into parallel relation with the sides ot the lasts vheel portion, and means for successively moving said heelstretchers to swing said wing portions around the heel ot the last, and apply them thereto, said stretchers contacting only the outer face of the vamp. Instrumentalities are also provided for closing the legs of the flexible' U-shaped toe-anchoring member to turn the margin of the vamp under the-edges of the sole and press it thereto,and members are provided for concurrently pullingthe vamp into the instep curves of the last. lA vertically moving, medially positioned knife, and actuating means therefor, are

provided for severing the excess stock from the Wings of the vamp as they are successively applied to the heel portion of the last, and

a seamroller, following the course of the' knife, is provided for rolling the vertical seam at the heel` ol the shoe after the knife has operated upon said Wing-portions vsuccessively. Last support.

'Referring first to Figs. 1l and 14, the machine here illustrated comprises a table 20, on the central part of which is mounted a pedestal 21, having 'at its top a shoe-last support 22ineluding a toe-rest block 23 and a lheel-rest block 24, the latter being carried on a slide so that it can be adjusted Jfrom and` toward the toe-^rest block to suit the length.

of different sized lasts, and the heel-rest block is provided With a pair of side gauges, onel being shown at 25, for lpositioning a shoe-last Q6 thereon. Said gauges, in any suitable manner, may 'be made adjust-able to accommodate shoe-lasts of different widths.

For holding the last 26 upon the-sup `ort 22, ai soft-rubber pad 27. adapted lto ear t upon the top of the last, is attached to the overhanging end of 'a clamping 'ariii 28 mounted to swing horizontally and slide verl tic-ally upon a post 29 rising from the table 20, said arm being urged upward on said post by a helical compression spring 30 and t adapted to be held down in clamping vposition, against the action .otsaid' spring, by a hand-.Wheel-nut 31 having seglnental threads (not shown) adapted. to engage a Toe stretcher. The vamp is shown, partly broken away,

at 34 in Fig. 2. The flexible U-sh'aped memi ber bfor anchoring the toe-margin of the vamp and swinging it over onto the last 1s designated-35 (Figs. 2, 3 and 4), its crosssectional form being clearly shown in Fig.

4. It is preferably of soft rubber, -whieh may be coated with rubber cement from time to time to assurethat the stock will adhere thereto, and in its opened out condition -tits within a bay eut in a. tiltable' and movable lplate 36, beingAsupported'therein by a curved series of small 'rectangular plates 37, 37 secured at their innerrends to the stocklanchoring member' and diverging outwardly therefrom, said plates slidably bearing upon the tiltable plate 36 and being connected with each other at their inner ends by links 38, 38, and at their outer ends by lost motion links 38, 38,- ,f

Saidsmall plates 37 are prevented from dropping substantially from'` the tiltable plate 36, when the latter is inverted, by reason of the middle one of them, locatedat the toe ot the vamp,"being `secured at its outer end to the tiltable plate 36by a pivot-pin 39, and the end ones of the U-shaped series being slidably held againstsaid tilt-4 member 35 throughout its length, the plates 37 spreading apart at their outer ends un- 'til stopped by the links 38a, and the legs of the U then'swinging toward each other. these movements being incident to the operation ot drawing the toe-margin of the vamp against the sole-edge of the last after the tilt-able plate 36 has vbeen turned over into vamp-applying position.

Instap pullers.

The tiltable plate 36 also carries a. pair `of instep-pull1ng pads 43, 43, adjustably' secured,- asv shown clearly in Figs. 2 vand 3,

49, -said slide-bars being mounted in apertures of the cr'ossshead shoe or guide-plate 491 and adapted freely to `slide therein as the heel-stretcher isturned between horizontal and vertical position about the moving pivot' The head 49t is adaptedvto abut the face of the guide-plate 49q to4 limit the movement the heel-stretcher toward the vertical position,I and the heelstretcher is provided with astop 49V adapted to abut the' v top of said guide plate to limit said heelstretcliers movement toward the horizontal position.

. For yieldingly holding the heel-stretcher 49 in either its horizontal or vertical position, while permitting it to be turned from the foriiier to the latter byits momentum or gravity when the mechanism is inverted, to

4twist' the wings of the vamp into vertical planes', and to be turned b ack by hand, itis connected by a pull spring` 49W `with the guide plate 49f1, 'said `spring acting overcenter with regard to the pivot 49m.

As shown in Fig. 6theheelestretcher 49is provided with a face-plate 49x which projvides its sliding surface .against the heel- Q stretchersuj'nporting plate 49d, and said face plate 49x is formed with an overhanging or half-'dove-'tail edge/19y adapted to interlock with a complementary doveftail flange -49Z on the plate 49d to prevent excessive strain on the pivot pin 495, said dove-tail edges or Cil flanges being curved substantially. concentrically with thepivot 49e (this feature not being shown, butvreadily understood by ref erence to Fig. 6), so that the heel-stretcher may turn about said pivot in adjusting itself to the last while sai-d dove-tail flanges continue in'en-gagement. Suitable stops shown, at 48, 48 (Fig. 9), as to the stretcher 48,

parts, so faras shown, are given the numeral 48 with the same enponent given with the numeral 49 in referring to the heel-stretcher 4a.

by their rcspectire rack-bars 48T, 49" andv slide bars 48, 49, from a skeleton, heelstretcher frame pivoted concentrically with the 'pivot of the plate 36, said frame comL prising two parallel pairs of slide-guiding, radius bars 50, 50, 51, 51, (see especially Fig. 2) connected at their outer ends by a cross-member 52 of angle iron, and corner blocks 52, 52a, land said cross-.member 52A v,ieafiee vserves as a handle in turning 'the licel stretcher. frame and the pivotedtoe-stocle supporting plate 86 over from the stocleA coinpressionspring 55 on the bar 50 or 51` and an opposed, adjustable `pull spring 56 (Figs. 1, 7, 8 and 9) connecting theslide with apart of the pivoted frame adjacent said-cross-bar.

. The rack bars 482 49r and slide-bars 48, of the heel-.stretchers are slidably mounted, at right-angles to the'slide-guidingframe-bars 50, 50, 51, 51, in suitable guide apertures in the respective slides 53,

A54, th'ejteeth of each of the rack-bars 48T, 49"4 being inc shed with a pinion, 57, 58, mounted in a recess in the slide and splined upon a shaft, 59, 60, said shafts being rotatably and slidably mounted inV the. respective slides parallel with the'radiusbars of the'frame and adapted tobe turned successively, by means hereinafterl described, after their frame has been Jturned' overv onto the 15st first to run the heel-'stretcher 48 transverse .ly of th'e'macliine, inward to its medial, lstock-applying position, then slightly. past forward against the last when it is so run in to its medial position, the heel-sti-etcher'having at this stage fallen into .the vertical position as shown, with regard to heel-stretcher- 48, in FigsY, 8 and 9, and with regard to the heel-stretcher 49, upside down', in' Fig. 6,.

ilu

each ofthe slides 58, 54 hasadjustably secured thereto a pull-bar or silde bar, the one for the slide 53 being shown at 60, parallel 'withthe radius bars of thepivoted frame, `the o ppositeend lportion of said slide bar being slidably mounted in a bracket 61 secured to the adjacent pair of radius bars, and said slide bar is provided with a laterally projecting cam roller 62 running' in the 'elbow of a cam-arm 63,Y the latter being pivoted upon a bracketl 64 secured to the adjacent rafdiirs bars and provided with a hinge spring A65 to hold itinassociation with the roller 62 as the pivoted frameis turned to the stock-receiving 'position-of'Fig. 1. .The outer end of t-he cam-arm 68, with the pivoted frame as positioned in- Figs. 7 and 8, is adapted to be engaged 4by a cam or 'dog 5311,hereinafter described, topull the slide 53 along the radius bars 50, 50, against the action ofthe pull spring 56, the 'reaction of said pull spring returning'said slide, against the vcompression spring 55 When the eamor dog 53b1 has passed from under the cam arm v63. 66`is the nearer of a pair of stoplposts for the pivoted frame above described, each of said posts havingea hollow upper en'd adapted lto receive a rounded stud 6l formed on the bracket 61 or its fellow at the other side of the machine. the nearer of which is shown at 66l (Figl) y y are mounted upon" the table 20 and adapted 'lao 4to crowd the respective slides 53, 54, against the springs v55, as the heel-stretcher frame reaches loading position (Figs. 1 and 2), to assure the accurate positioning of the heelstretchers to receive the vamp.

Ach/,ating mechanism.

As above' stated, the pivoted frame ,carrying the heel-stretchers and the tiltable plate 36 carrying the toe-stock anchoring member are concentrically pivoted and they are adapted to move bodily as Well as to turn over their pivot, near the toe of the stock, from their stockreceiving position of Figs.

-1 and 2 to theirstocloapplying position of Figs. 7, 8. and 9. When said frame is stopped in its pivotal movement by the posts 66,' at which time the heelstretchers by reason of their-.momentum and weight snap into vertical position, overcoming their overcenter springs 48W,`49W, and thus hold the wings of the upper alongside and parallel to the heel of the last, the plate 36 requires to be further turned downward, from its position in Fig. 7 to its position in Fig. 8` to carry the toe margin down to the sole ot` the last. l

The plate 36 is provided atits respective sides with parallel arms 67, 67 (Fig. 2), ap-

proximately in its own plane, said arms being aperturedand mounted upon respective stub shafts-68, 69. rlhe arm 67 is secured against rotation upon its stub-shaft 68 by a pin 67", while the arm 67a is rotatably mounted upon its stub-shaft 69.` Said arms extend beyond said shafts, their outer ends being provided with transverse, springbacked plungers or latching pins 70, 70. Said stub shafts are rotatably mounted in respective bearing" brackets 7l, 71 rising from a carriage 72 extending across the-table 2O under the parts heretofore described and.

supported on said table at the far side, as viewed in Figs. 2 and l0, by rollers 73, 73 running on suitable. track-ways and at the near side by a rail 74 upon which the carriage slides. Adjustable stops 75 (Figs. 2, 7 and 10) and 76 (Figs. l and 10) `are mounted upon the table 20 to limit the movef ment ofsaid carriage, and ac pull spring 7 2a connecting it with a part ot' the table is adapted to urge it toward the last pedestal Cam members,

21, whichv is to say toward stock-applying.

position.

Each pair of the parallel radius bars 50,. 50, 51, 51a of the pivoted frame is provided with a bearing member 77 (Fig. 8) clamped upon the inner ends of the bars, said bearing dimple adapted to receive the adjacent one of the springspressed latching pins' 70 Vto hold the plate 36 and the heel-stretcher frame' substantially parallel as they are swung over from the position of Figs. l' and 2 to that of Fig. 7, but by the forcible dislodging of said latching pin from said dimple to permit the further turning of said plate to its position in Fig. 8, against an adjustable stop 36a, after said frame ,has been stopped by the posts 66, and likewise to hold them substantially parallel in the corresponding part of the reversemovement.

For `assisting the movement of the carsus5 riage 72 and so assisting the over-swinging y' pivotal movement of said plate and frame effected by means of the handle bai-520iV the latter, and for the further turning of .the plate 36, as well as to actuate certain cam-carrying frames hereinafter described, the stub-shaft 69, which it will be observed is looselyyjournaled in the members heretofore mentioned, has secured on its outer end a hand wheel 78 and a gear 79, the latter meshing with a two-faced rack bar 80, having teeth 8Oa on its top face and teeth 8Ob on its bottom face, said rack bar being the base or lower, horizontal member of a generally rectangular, vertically positioned, skeleton, cam-carrying frame 81, through the central open space of which the stub-shaft 69 eX- tends, said rack being slidably mounted, forv longitudinal movement on the table 20, between Vgrooved guide-rails 82, 82 secured upon said table. 68, has adjustably secured on its outer end a gear 83, of less diameter than the gear 79, the slots and screws for its angularadjustment being shown respectively at 83a, 83b (Fig. 1). Said gear is meslied with a rel-a- .tively short rack 84 adjustably secured by bolts 84a, 84 (Fig. l) uponthe lower,hori zontal member 85 of a generally rectangular, vertically positioned, skeleton, Camrarrying Jframe 86, through the central open space of which the stub-shaft 68 extends. Said lower horizontal, cam-carrying-frame Amember or rack bar 85 is slidably mounted for longi- The opposite stub-shaft,

pending from the table 20, under the rack members 80 and 85, is a transverse shaft 89 having secured on its respective ends gears 90, 90 of equal size, meshed respectively with the bottom rack teeth 8G", 85b of the rack members, 80, 85, and thus adapted tocompel the parallel cam-carrying frames 81, 86 to move equally, the trame 81 being driven by the gear 79. 1

Rotatably mounted upon the stub-shafts 68 and 69 respectively,'just outside of the respective brackets 71 of the carriage 72,

are plates, that for the'stub-shaft 6 9 being shown at 91 (Fig. 2), to which plates are adjustably secured, by means of screw bolts 91, 91a (Fig. 2, 7 and 8),'respectivevsegmental, bevel gears, one of the latter being shown/ at 92, said segmental gears being.

provided with respective radial cam arms 93, 94 each provided with a laterally projecting cam roller, 93u, 94, on its outer end, said rollers being adapted to be engaged by respective cams presently to be described for turning said segmental gears. The shafts 59, 60, above described as being" adapted, through the pinions 57, 58 respectively splin'ed thereon, to run the lieel-stretcherstransversely of the machine, rotatably extend through the respective brackets 61A above described and also through respective brackets 95, 95 slidably mounted on the adjacent radius bars 50, 50 or 51, 511 of the heel-stretcher trame, near the segmental gears 92, and Veach of said shafts has secured on its inner end a beveled pinion 96 meshed with the adjacent segmental gear, the latter beingthus adapted, when turnedby its cam, above referred to and hereinafter described, to drive the shaft 59 or 60, and thereby run the heel-stretcher 48f or 49 toward the middle of the machine. 7der returning the heelstretcher to the side of its frame, when the cam roller 93n or 94=L is freed from its cam, so that the heel-stretcher will clear the last as the frame is swung back to loading position, and will be positioned to receive the next flat upper, a helical torsional spring 97 is mounted upon each of the rsha-tts 59, 60, and has its respective ends anchored in a collar 98 secured upon the'shaft in abutment With the slidable bracket 95, and in a knurled Washer 99 slidably and rotatably mounted upon said shaft and provided with' adowel 'frame,' the beveled pinion 96 may b e unineshed with its segmental gear by sliding 1 said bracket and the shaft outward against the thrust of the spring 97and then allowed to return into mesh with the said gear undei' action of said spring at a diierent point on the gear, the latter meanwhile being given-.

a partial turn, to adjust the position of the corresponding heel-stretcher with relation to the cam-arm, 93 or 94, of the gear.

The arrangement so far described is such that, with the tiltable plate 36 and the heelstretcher frame and related parts in loading position, as shown in Figs. 1 and 2, the overswinging of the handle bar 52, which may be indirectly assisted as stated by turning the.

hand-wheel 78 counter-clockwise as viewed in Fig. 1 ermits the pull-spring 72 (Fim 10) to piiliJ h n last- 26 until it abuts' the stop 75 (Figs. 2 and 10)the gear 83 turning with the plate 36 and running on the rack 84, which is thecarriage 7.2 toward the shoev stationary until the over-swung traine is stopped b y the posts 66, while the larger gear'79, its -stub-shatbeing loosely jourand the bearing naled in the plate-arm167a lil() member arms 77 andy-77", runs an equal distance but at less angularspeed, upon the upper teeth-of the now stationary' rack-bar 80,;the `cam-carrying frames of which these* rack members'` are partsbeing at their lettliand limit as viewed iii Figs. 1, 7 and 8.

Stock-trimming cm'fe.

` I The knife 33 heretofore referred to, Vfor 'trimming the excess stock from the wings or heel portions of the upper as they are successively applied to the last, is shown' in Figs. 14 to 17. It is secured on the outer end of the upper arm 124a of a bell crank lever 124, the latter being fulcrumed at 1241 between fork arms formed on the upper end -of a vertically slidable bar 125 mounted in a guide-way formed in a bracket 126 depending from the table 20 and provided with a retaining plate 127. The lower arm 124C of the bell-crank lever 124 has ,its outer end connected by a link 128 with an arm, 129, se-

cured upon a rock-shaft 129a journaled inl 'the cam 133 or 135,

brackets, onev of which isshown at 130, mounted upon the table 20.y Another arm, 129", projects laterally from the other end of said rock-shaft and is provided with a laterally projecting cam roller 131 adapted to be engaged by successive pairs of cams 132, 133 and 134, 135 (Figs. land 14), on the cani-carrying frame 81, during the forward movement of the latter,'to the right as viewed in Fig. 1, to actuate the knife as the heel-stretchers in succession apply the wings of the upper to the last, the knife-supporting arm 124g, being, in each cutting operation, ,first thrown to vertical position and then raised with the bar 125 by the cam 132 012134, and then swung against the work and'drawn downward'bythe cam 133 or 135.

The vertically slidable bar 125 is provided at its upperend with adjustable stop bolts 136, 137, adapted to limit the angular movement ofthe bell-crank lever 124 at the positions shown respectively in full lines and in dotted lines in Fig. 14, and the lower arm 124c of said lever is connected by a pull spring 138 with4 the lower .end of the bar 125, to hold the lever 124 against the stop 137 when the cam'roller A131 is free from its cam. Said spring also assists the arm 1 29 in holding the knife 33 against the lwork as said knife is drawn downward, in its cutting movement, Withits supporting bar 125, by The vertically slidable har 125 is provided with alone way brake, 139, the details of which are shown in Fig.

18, adapted to resist' its downward move-l ment so as to assure that the downward pull of the arm 129 upon the bell-crank arm 124c will hold the knife firml against the work while pulling said `knife downward with the slidable bar 125 upon which it is mounted. Said brake comprises a friction member 140 adapted to bear against the bar 125, said member being mounted upon a backing member 141 mounted in a slot 142 in the bars retaining plate 127, and said backing member being formed on its outer face with a recess containing a metal ball 143 bearing against an inclined plate 144 secured to the retaining plate 127, this arrangement being such that the downward force exerted by the bar 125 upon the friction member 140 wedges the latter with its backing member 141 and its ball 143 between the bar 125 and the inclined plate 144, thereby increasing the pressure and braking effect of the member- 140 upon said bar. 1t will be seen that the upward movement of the bar 125, on the contrary, in upwardly displacing, these wedging members, reduces and substantially nullities their braking edect. A compression spring 145 is interposed between the backing member 141 and a bracket 146 thereover, said bracket being secured to the retaining plate 127 for lightly holding the Wedging members in braking position so as" sol vdrag of the bar 125.

I meente Knife heater. *Toy facilitate theV cuttingfo the knife 33 a burner1471fis knife, asshown in Fig. 14, whensai'd knife is in the full line position there shown,

.which it assumes between cutting operations.

A cover 148, slottedto receive the knife arm 124, is provided. for said burner.

Seam-rolling device.

The seam rolling device, shown in Figs. 1 and 19, comprises a rough-treaded roller 149 mounted on the end of one arm, 150,

of al bell crank lever 150,-the latter being fulcrumed at 150b on a slide 151 mounted for vertical movement upon the p'ost 29 and constantly' urged upward by a weight 152 connected with said slide by a chain 153 running over a` pulley 154 loosely journaled on said post. bell crank .lever is connected by a link 155 with an arm 156 projecting from the inner end of a transverse rock-shaft 157, the latter being mounted in suitable brackets, one being shown at 157, upon the table20, the outer end of said rock-shaft being provided with a camp-actuated arm 158 provided with a laterallyprojecting cam roller 159 adapt--- ed to be engaged by a cam 160 pivoted upon a bracket 161 carried by an extension of the cam-carrying frame 86,y during the leftward or return movement of the latter, to throw the roller 149 againstl the work and draw it' downward along the heel seam, the slide 151 being drawn downward, lifting the weight 152, as the downward pull of the link 155 continuesafter the roller has been swun into contact with the work. The rock-sha t 157 is provided with a suitable torsion spring 157", mounted thereon and having its ends anchored in said rock-shaft and in one of its brackets respectively, tocause the arm 156 to rise as soon as the roller 159 passes from its cam, to clear the work as the slide 151 is returned upward by the weight 152.

Mownt/ag of pz'cotedv cams.' The cam l160, in `order that it may pass over the roller 159 inoperatively during the first, forward movementof the cam-carryin O frame 86, and in order that its position and pitch may readily be adjusted, is -pivoted upon a stud' (not shown) eccentrically positioned upon the innerside of a ld1se 162 rotatably mounted in the? bracket 161, the outer side of said disc being provided with a lever 163 -having a'slotted' outer end'in which'is mounted a clamping bolt 164 pro# i lposition'ed' on the table 20 that its rviiane'fwill heat said'.

The other arm, 150", of the' at corresponding positions. (The cams 132 and 134 are similarly pivoted, sothat they may pass inoperatively over the cam roller 131 of the cuttinggdevice during the return `movement of their frame 81, their pivot "studs being shown respectively at 1322 134a (Fig. 1), their discs at 132,", 134", and the clamping lever for the cam 132 being shown in Fig. 14 at 132. The vertical plates upon which thesecams are mounted are formed with several arcuately arranged clam ingbolt holes to increase the range of a justment afforded by the slots in the ends of their levers, such holeswith respect to the Cam 132, being shown at 132, 132d in Fig. 14, and the clamping bolt, 132e, being adapted to be` mounted in any of said holes.

Last gauge. For facilitating the exact positioning of the shoe last 26 with respect to the vampapplying mechanism, a forked gauge member 165 is hinged upon a bracket 166 secured to the edge of the plate 36 which is adjacent the last when said plate is in loading position, as shown clearly in Fig. 2, the forks of said gauge member being adapted to receive ythe toe of the last between them as there shown. v Said g..uge member 1s pr0- vided with a hinge spring 167 to permit it yieldingly to contact the sole of the last, without raising the latter, when it is brought up to the toe of the last by the turning of the plate 36 back to loading position.

An angle iron 168 secured to the table 20 (Fig. 1) is adapted to serve as a stop or lrest for the handle-bar 52 of the heel-stretcher frame when the latter is in loading position.

Operation.

In the operation'of the machine, the parts .being in the position shown in Figs. 1 and 2, the upper or vamp, 34. with its last-contacting side uppermost, is laid upon the supporting block 34", about the gauge 34C, as shown best in Fig; 2, and its margins adhesively anchored to the toe-stretcher 35, and the heel-stretchers 48, 49, the knife backing plate 49h being swung on the pivot 49j to admit the stock and then permitted to close upon the latter under action of its spring 49k. The shoe last, with the inner parts of a shoe thereon, is mounted upon the pedestal 21 and clamped thereon by means'of the arm 28. The camcarrying frames 81, 86 are at their leftward limit, as viewed inv Fig. 1, wherefore the weight of the heel-stretcher frame, the plate 36, and their associated parts, holds the car' riage 72 at its right-hand or outward position, against or adjacent the stop 76, against the pull of the spring 72a. -The heel-stretcher frame, together with the tiltable plate 36 and their associated parts, are then swung over toward the last by means of the handle l bar 52 to invert the vamp and present it from above to the last. During this overswinging movement the gears 79, 83 run respectively upon the now stationaryracks 80, 84, the vamp thus being moved bodily toward the last as well. as turning over, and the carriage 72, being pulled by the spring 72a, correspondingly moves toward the last until it abuts the stop 75. When the carriage is .thus stopped, or immediately thereafter, the turning movement of the heel-stretcher frame is suddenly'stopped by the posts 66, and the weight and momentum of the heelstretchers thereupon causes them lto snap into vertical position as above described."

Further turning of the hand-wheel 78 v in the samedirection, the carriage being stopped as stated, drives the cam-carrying frame 81,'thr0ugh the gear 79 and rack teeth 80, to the right as viewed'in. Fig.` 1,- and through the rack teeth 80", gears 90 o n the Shaft 89, and the rack teeth 85", drives the cam-carrying frame 86 in thev same direction and atthe same speed as the frame' 81. This forward movement of the frame 86, through the rack 84 thereon, drives the gear i 83 and thereby further turns the plate 36,

about its now stationary pivot, from its po- ,sit-ion in Fig. 7, to that in Fig. 8, to pull the cam 109 contacts the roller.104b and through parts abovel described closes the toe-stretcher 35 and, instep pullers 43 inward with respect to the last to pull the uppervstock respectively about-the edge-of the toe-portion or the last and into the instep curves of .the latter. This action' completed, the dog 119a strikes the arm 119, thus releasing the clutch 112, 113, through parts above described, and permits the weight 109 to return the rack 108 for the next operation.l

yAt aboutv the same time that. the toestretcher and instep pullers are thus, operatedv the forward movement of the frames 81, 86, to the' rightjas' viewed in Figs. 1,7 and 8, brings first the cam 86a into contact with the roller 93a on the arm 93, which latter has been thrown to its lower position by the4 over-swinging of the heel-stretcher frame, and said ycam, through parts above described, runs the heel-stretcher 48 inward to a medial position, and while it is so held by the Straight, middle portion of said cam, as shown-in Fig. 8, the cam 53a contacts the arm 63 to move the heel-stretcher 48 forward against the last, through parts. above described, 'and so hold it while the knife 33 is actuated and withdrawn by the cam 132, 133.

The terminal rise 86t of thefcam' 86a then shoves the heel-stretcher 48 v,slightly beyond its medialv position, substantially to the posi tion indicated by broken lines at--86g in Fig 9, to disengage the lsevered' margin of stock from the work. The pull spring 56 then retracts the heel-stretcher 48 rearwardly from the last and, the cam 86n leaving the roller 93, the spring 97 runs the-.'heel-stretcher back, laterally of the machine, to a 'position adjacent the frame bars 50,y 50a.

Similar operation of the heel-stretcher 49 is then effected by the cams 81a, 54, and corresponding parts, the knife 33 being now actuated by the cams 124,135, during the further outward movement of the frames 81, 86 When. the latter have reached the forward limit of their movement, the hand-wheel 78 is turned in the opposite direction, clockwise as viewed in Fig. 1, to return said frames to their leftward limit as there viewed, and during this return movement the cam 160 actuates the seam roller 149 through -mechanism above described. When the frames 81,` 86 have `reached their leftward limits as. viewed in Fig. 1, further clockwise turning of the hand-wheel 78, assisted by means of the handle 52,` runs the gears 79, 84 upon their respective racks, the carriage 72 moving against the pull ofthe spring 72a, and the heel-stretcher frame and the plate 36,

with the parts carried thereby, are thus swung back to loading position, the cam members 66EL augmenting the pull springs i to cause the proper positioning of hee stretcher slides. The last with the work thereon ,is then removed, and the operationA asdescribed is repeated.l

While the fore oing description relates to a last which is a hesively prepared by having the lining and theinsole mounted thereon as it comes to the machine, it will be apparent that the invent-ion -is, independent of the presence or absence of these inner shoe parts, and for the sake of brevity and clarity of expression the term lastr will be used .in the appended claims as applying to a last either with or without these inner shoe parts thereon. The word upper also is intended to include an upper shoe part such as a lining.

It is also to be understood that appliean has-used the word lasting inthe appended claims inits broader sense, as relating` to the application of' shoe parts to lasts, and not in the more restricted sense of securing the margin of the upper to the insole.

An especial advantage'of the heating of the knife is that it permits the knife to trim the first-applied heel margin, with the last and the shoe lining thereon serving as a backing plate forthe knife to. cut against, l

as shown in Fig. 16, without such sharpness holding it extended throughout itsarea by en of the knife or such force of the knife against 7. enga the lining or the last asl to cut or score the' same, the heat of the knife causing the rubber to soften so .as to cut easily and permit the passage of the knife without 'drawing' and wrinkling of the cut margins by frictional contact with 'the knife.
